NineGaps is a Math Puzzle Game, just like Sudoku but different, for the iPhone. If you like Sudoku or Ken-Ken puzzles you’ll probably also like NineGaps.
NineGaps has three different levels and an unlimited number of math puzzles for you to solve. Use your brain to place numbers from 1 to 9 in the missing gaps, while matching the math operations presented on sides of the puzzle. Happy Puzzling!
